` I Application led September 28. 1901. Serial No. 76.867. (No model.)

lo tu whom t may concern.-

Be it known that I, THOMAS EDWARDS, a

. subject ot' the King of Great Britain, and a resident of Sebastopol, Ballarat, State of Victoria, Australia, have invented certain new and useful Improvements in Generators for Chlorin Gas, of which the following is aspeciication.

It is the object of my invention to provide a generator for chlorin gas capable of with-- standing great pressures and in which the gas maybe continuouslyand uniformly generated and may attain a high degreeof pressure.

In nearly all cases where chlorin gas is gen,- erated in large quantities the chemicals used have to be stirred to keep them from caking or packing in the generator. This has hith-` erto been done when necessary by hand to facilitate the operation of producing the gas. In breaking up the caked chemicals a rush of gas is the result, which makes the flow of gas intermittent, while the operation of breaking the cakes is a most disagreeable occupation and is always avoided by the workmen where possible, while the cleaning out of the spent charge is even worse. To prevent this, I have constructed a mechanical generator which oscillates on its trunnions, the said trunnious resting on supports, and the motion thus given to the chemical contents keeps thecharge from caking, and consequently there is amore constant flow of gas. I have sought to provide a simple construction which will comprise a strong iron shell or casing and a lead lining therefor. I have had in view also to provide such a generator as will allowr the op' eration of charging or cleaning out to be readily performed and also to make provision for the cooling of the generator.

In the accompanying drawings, Figure l is a side view of the generator. Fig. 2 is a plan view of thecover. Fig. 3 is a central vertical sectional view.l Fig. Il is a plan View with the cover removed. Fig. 5 is a sectional view of the lead lining before it is attached to the cover. Fig. 6 is a view of the cover, showing the clean-out openings in section.

is a detail sectional View of a modication, showing the manner of introducing the acid through'the hollow trunnion.

The generator is, as shown in Fig. l, of substantially semicylindrical shape, having charging-opening.

Fig. r.A

a rounded bottom l anda flat cover Itis provided with journals 4, the fia'uges of which are bolted to the sides of the iron casing at 5. 'Fliese journals are intended to rest iut suitable bearings, and thus su pport the generator in such a manner that it may be rocked or oscillated on said journals, for which purpose one of the journals is provided with an arm 5, having a pin or roller 6 to be engaged by the hooked end of any suitable operating rod or pitnian?. By this arrangement the generator may be rocked Aand the contents thus kept constantly in motion `and agitated, so that the ditt'erentportious of the manganese .will be exposed to the acid and the generation of gas will go on continuously and substantially uniformly until the materials become exhausted.

It will `be noticed from Fig. 3 that the generator is composed of side, bottom, and cover plates of iron orother suitable material bolted together, angle-iron pieces 8 being preferably used at the joints between the plates. The iron casing is provided with lead lining pieces or plates, the bottom lining-plate 9 having flanges Yl0, which, together with the lower edges of the side lining-plates 1l, tit between the parts of the outer shell and are all bolted together. The side lining-plates at their upper edges have horizontal iianges fitting between the parts of the outer shell and are likewise bolted thereto by the same bolts l2 which secure the parts of the shell together.

The lead lining 14 for the inner side of the cover-plate lis of special formation and is shown detached in Fig. 5 and in the form in which it ismade ready for attachment to the cover-plate, as will be described hereinafter. This coverplate is provided with a plurality of openings. One of these (marked 15) is a This is arranged near one edge of the cover and about midway between the side edges. At the opposite end of the cover two clean-out openings 16 are provided, these being on opposite sides of and equidistant from the center line of the cover. A fourth opening 17 is provided centrally of the cover through which the acid is introduced and through which also the chlorin gas escapes. Each of these openings, as Well as the inner side of the cover, must be properly lined with lead, and for this purpose the lead lining, Fig. 5, is provided with a series ol collars 18, extending up therefrom to project through the openings in the cover. The projecting ends of these collars are then upset upon the outer side of the cover, thus forming Washers of lead completely su rrounding and protecting the edges of theA openings. The lead lining also has stems or integral rivets 19, which project up through openings 2O in the cover, and these are headed down upon the outside of the cover-plate, thus securely holding the lining thereto at all necessary points. The charge and clean-out openings are closed by plates 2l, clamped down tightly upon the lead seats of the lead Washers by screws 22 passing through crosspieces 23, Which are supported in the brackets 24, secured to the upper surface of the cover.

The cover of the generator at its center is surmounted by a dome, the lower liange of which is seated upon the outer fiange of the centrally-arranged lead Washer. This. dome is held in place by dogs 25, secured to the cover and engaging the flange of the dome. Through the top of this dome the inlet-pipe 26 for the acid extends, and the outlet-pipe 27 for the gas leads olf from the top of the dome. Both of these pipes extend to the journals and are clamped in brackets 28, Which rock with the generator. thus maintain their position in relation to the generator in all the positions the latter may assume.

The bottom lining is slightly separated from the bottom shell of the generator by ribs 28, which are interrupted at intervals by cross grooves or cuts. By this construction Water may circulate to different parts of the bottom of the generator to keep the same cool, said water being let in and discharged through the pipes 29 30, respectively.

By the generator as above described it will be seen that the contents can be kept constantly in a state of movement or agitation to expose different parts for the production of the gas. When it is desired to clean out the generator, it can be swung so that the contents can be discharged through the clean- These pipesout openings. There being two of these, it will be possible to reach the different sides or corners of the generator to loosen any of the material which may adhere to the Walls. In this cleaning operation also the charginghole may be opened, so that light may enter to facilitate the work. By having the gaspipe. lead off from a dome surmounting the generator instead of from the generatingchamber directly no particles of the materials used in the generation of the gas will pass off from the generator, as might be the case -Were the discharge effected from the generatingchamber proper.

In Fig. 7 I have shown an arrangement by which the acid may be introduced through the trunnion of the generator, the acid-pipe being shown as extending longitudinally through said trunnion, a suitable stufng-box and gland being provided at 3l to make a tight joint.

I claim as my inventionl. In combination, the casing, the cover having openings, a lead lining having Washers extending around the edges of the openings, a dome over one of the openings seated upon the lead Washer, and a clamped cover on the washer of the other opening, substantially as described.

2. Incombinaton,thecasinghavingacover with an opening, a lead lining having integral rivets headed on the outside of the cover, and Washers extending around the edge of the opening, substantially as described.

3. A generator for chlorin gas and the like of semicylindrical form having a flat top, journals near said Hat top projecting laterally and upon which the generator may rock, a dome snrmounting the said dat top, a gaspipe leading therefrom and a covered opening in the iiat top to one side of the dome, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
